100003 - KEY NOT EXIST

A 100003 - Key Not Exist error typically appears on a tapped or contactless card-present transaction when the device's contactless limit is exceeded. Follow the guidance below for both an immediate workaround and a long-term fix.

Error Message: 100003 - Key Not Exist

Environment: Typically occurs on a card-present transaction that is tapped/contactless.

Root Cause: The Contactless Transaction Limit that is configured on the device has been exceeded.

How To Resolve: To process the transaction being attempted, dip the card instead of tapping. This bypasses the contactless limit issue. For a long-term fix, send us a request on the Launchpay Support Portal with the error message and transaction details. Our team will work with you on increasing the transaction limit configured on the device.
